RECTlFlER FOR SPIRIT-STILLS.

SPECIFICATION forming part of Letters Patent No. 689,010, dated December17, 1901.

Application filed July 1, 1901. Serial No. 66,711. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT LES'ZER, acitizen of the German Empire,residing at Gummersbach, in the Province of Rhenish Prussia, Kingdom ofPrussia, Germany, have invented certain new and useful Improvements inRectifiers for Spirit-Stills; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in rectifiers for spirit-stills;and it has for its object to produce a better dephlegmation of thespirit-vapors and to increase the quantity of spirit obtainable from acertain amount of mash. In order to attain these objects, I havedesigned the new rectifier as shown on the accompanying drawings, inwhich Figure 1 is a vertical central section along line I I of Fig. 2.Fig. 2 is a horizontal section along line II II of Fig. 1.

The rectifier consists of a hollow cylindrical vessel 1, which is closedat the top by a cover 2. This vessel is fixed upon the still, (indicatedin dotted lines in the drawings,) from which the alcoholic vapors riseinto the rectifier through a pipe 3, in which case the rectifier isplaced immediately upon the still. Inside of the vessel 1 are placedconcentrically three other hollow cylinders 4c, 5, and 6, respectively.These three inner cylinders are so arranged that they can be withdrawnout of the vessel 1 when the cover 2 is taken off. By this arrangementthree annular spaces 7, 8, and 9 are formed between the cylinders. Thespace 8 between the two cylinders 5 and 6 is closed at the bottom by acover 12, and the cylinders 6 and 4 are so connected together or. closedat top by a cover 10 that the annular spaces 7 and 8 communicate witheach other, the intermediate cylinder 5 not reaching quite up to thecover 10. The annular space 7 between the cylinders 4 and 5 is closed atbottom by a flange 11. The circumference or mantle of the cylinder 6 isprovided with pockets or plates 13 of half-round or oval shape andprojecting alternately on diametrically opposite sides to the right andto the left so far that their peripheries touch for about half a circlethe inner circumference of the cylinder 1, the other half leaving a freepassage between the vessel 1 and the cylinder 6, so that fluids orvapors rising between 1 and 6 are forced to make the zigzag courseindicated by the arrows in Fig. 1. The inner cylinder-4 has ahemispherical bottom 15, and into the space 17 inside of this issuspended from the top or cover 2 the exhaust-tube 18, which is open atthe bottom and widened. From this it will be seen that the vapors risingup in a serpentine line between 1, 6, and 13 pass over the cover 10 andthen descend into the space 17, whence they rise up again and pass outby the tube 18.

The annular spaces 7 8 and the space of the pockets l3 serve to receivethe cooling fluid, which may be cooling-water or fresh mash. It isintroduced into said space 7 by the pipe 19, rises up therein, andpasses over the upper edge of the cylinder 5 into the space 8, whence itdescends to escape by the pipe 20. The pipe 21, inserted at the top ofthe cover 10, serves for leading oft air, vapor, or gas which may havegathered in the annular spaces 7 and 8.

It will be seen that the alcoholic vapors pass through the apparatus inthe opposite direction to the cooling fluid, making thereby the longserpentine Way, and over the enlarged cooling-surfaces of the pockets13, so that waterand empyreumatic substances and other detrimentalmatters can be deposited or separated from the pure alcohol.

The condensed fluid which is collected in the space 17 is led back intothe space 9 by the pipes 22 and 22, so that it can be reevaporized, orit can be let offbyithe pipe 23, cocks or valves 22 and 23 beinginserted, as indicated.

All parts of the described apparatus are so connected and jointedtogether that they can be easily taken asunder for inspection andcleaning.

Having thus described my invention, I declare that what I claim, anddesire to secure ICO ference, the inside periphery of vessel, 1, acylinder, 5, placed inside of cylinder, 6, and connected to the latteran annular bottom plate 12, but open at theupper end, a cylinder, 4,placed inside of cylinder, 5, and reaching up with its upper edge tothelevel of the edge of cylinder, 6, and being connected to this by acover, 10, so as to leave a free passage over the edge of cylinder, 5,and between said cover, 10, a bottom flange, 11, connecting thecylinder, 4, to cylinder, 5, so as to close the annular space, 7,between these two cylinders, a hemispherical bottom, 15, closing thelower end of cylinder, 4, an exhausttube, 18, for alcoholic vaporsreaching into cylinder,4,and passing out through the cover, 2, ofvessel, 1, an inlet-pipe, 1!), for cooling fluid passing throughthevessel, 1, and reaching into the annular space, 7, between thecylinders, 4L and 5, an outlet-pipe, 20, for leading the cooling fluidfrom the bottom of the annular space, 8, between the cylinders, 5 and 6,out, of the apparatus and a connecting-pipe, 22, allowing usefulcondensed products to return into the zigzag passage between the vessel,1, and cylinder, 6, and leading off, by a branch, 23, the empyreumaticsubstances and other detrimental condensed products, the Whole asdescribed and illustrated and for the purpose set forth.

In testimony whereof I have aflixed my signature inpresence of twoWitnesses.
